Application filed December 15,1923. Serial No. 680,857.

To all whom it may concern:

Be it known that 1, JOHN O. MoCoY, a citizen of the United States, residing at Atlanta, in the county of Fulton andState of Georgia, have invented certain new and useful Improvements in Cotton Stampers, of which the following is a specification.

This invention relates to improvements in cotton tramper, and has for its objects to provide a mechanism for packing cotton which is simple in construction, can be easily operated both in its up and down movements and durable because of its steadiness in operation.

These and other objects hereinafter set forth are attained by the means illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the device showing a portion of the press box in section.

Figure 2 is a sectional View taken on the line 22 of Figure 1, and

Figure 3 is a plan view of the device.

Similar reference numerals in all of the figures of the drawing designate like parts.

In the drawing, 5 designates the press box in which the material is packed by the press block 6 fixed securely to the lower end of a stem 7 by suitable metal brackets 8 which are preferably mounted on all sides of stem 7.

The stem 7 is adapted to reciprocate be tween a pair of supporting beams 9 and is accurately guided therebetween by a pair of guide castings fixed to the upper and lower sides of the beam, each one of which is provided with a rectangular tubular por- 'tion 10 which loosely surrounds the stem and a base flange 11 by which it is secured in place. These guide castings are also provided with a series of double guide rollers 12, which are mounted between ears 13 projecting from the outer faces of the castings and project through suitable apertures 1 1 formed in the walls of the casting and en gage the sides of the stem 7 These guide rollers are arranged on all sides of the castings, and therefore engage all sides of the stem at points above and below the supporting beams 9, thereby preventing any tilting movement of the stem in its movements up and down.

The press block 6 and its stem is preferably operated by steel cables 15 and 15' whose sides are secured to a winding drum 16 mounted on the upper side of the supporting beams 9 a considerable distance from the guide stem 7 and suitable eyes 17 fixed to the base flanges 11. The respective ends of the cables are secured to opposite heads of the drum 16 in a manner to permit one cable to unwind while the other cable is winding, so that when the drum 16 is rotated in one direction one cable will wind to lift the press block 6 and the other unwind to permit the lifting, and when the drum 16 is rotated in the opposite direction, the press block will be permitted to operate downwardly. The cable 15 extends from the underside of the drum 16 to and over a pulley 18 mounted on the beams 9 adjacent the upper guide casting, and then downwardly around a lift pulley 19 supported at the lower end of the stem, and then upwardly to the flanges 11 of the lower guide casting where its end is secured in the eye 17. The cable 15 extends from the upper side of the drum 16 to and around the lower side of a pulley 20, then upwardly to and around a press pulley 21 mounted on the top end of the stem 7, and then downwardly to the eye 17 fixed to the flange of the top guide casting.

Any suitablemeans can be used to drive the reversible drum 16, such as the usual clutch pulley 22 as shown in the drawing.

It is thought from the above description the operation of the device is perfectly obvious, as when the drum is rotated in one direction the presser block is lifted to permit cotton to be placed below the block, and when the drum is rotated oppositely, the presser block is forced downwardly to compress the cotton in the box.

It will be observed that the operating cables 15 and 15 pass over the rollers 19 and 21 at the respective ends of the stem, thus providing a rolling contact at the ends of the stem and which causes the stem to be pushed upwardly and downwardly in a true line without any tendency of binding, which wouldbe caused by side-pulling should the cables be attached to the ends directly. This 1 arrangement permits a free and easy move ment of the stem through its guides and pie vents wear upon the sides of the stem.

Having thus fully described the invention, what is claimed is 1. A cotton tramper, comprising a presser block, a stem for said block, a guide casting having rollers to engage said stem on all sides for positively guiding said stem in its reciprocating movements, a pulley positely movable cables engaging ovensaid pulleys With a rolling contact for positively thrusting said stem in both directions.

2. A cotton tramper coniprising a presser block, a stem for said block, means for guiding said stein in its reciprocating movement, a pulley mounted at each end of said stem, guide pulleys mounted adjacent said guiding means oppositely movable cables engag- 1 ing said guide pulleys and stem pulleys and having one end secured to'eyes fixed t0 the frame atone side of said stem and to a reversible drum at the opposite side of said stem. p

In testimony whereof I aflix my signature.
